These are crowling on the bottom of my pond in the backgarden. We live in Eindhoven The Netherlands.
Please can you tell me what bug this is?

Dear Ine,
You have photographed the larva of a Caddisfly. Caddisfly larvae are aquatic and they build cases from various materials, including sand, gravel, shells and twigs. Each species of Caddisfly builds a different type of case. Because of this trait, Caddisfly Larvae are frequently called Caseworms.
